    • getTableCellRendererComponent

      public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
      Returns the component used for drawing the cell. This method is used to configure the renderer appropriately before drawing.
      Specified by:
      getTableCellRendererComponent in interface TableCellRenderer
      Parameters:
      table - the JTable that is asking the renderer to draw; can be null
      value - the value of the cell to be rendered. It is up to the specific renderer to interpret and draw the value. For example, if value is the string "true", it could be rendered as a string or it could be rendered as a check box that is checked. null is a valid value
      isSelected - true if the cell is to be rendered with the selection highlighted; otherwise false
      hasFocus - if true, render cell appropriately. For example, put a special border on the cell, if the cell can be edited, render in the color used to indicate editing
      row - the row index of the cell being drawn. When drawing the header, the value of row is -1
      column - the column index of the cell being drawn
